ah ok i get you, so a ported head with double valves springs, twin 40 webers and the rite cam is the way to go. i may possibly go larger valves not sure. but based on standard valves a 8000rpm cam is good. any recommendations? any of the ones from the website i linked in my first post?

ok i think i got it, thanks

and with the head porting how much is required? should i leave that to whos doing my head work?

thanks again
